WINDOW-SCREEN.

y SPECIFICATION forming part of Letters Patent No. 435,943, dated September 9, 1890.

Application filed March Z1, 1890. Serial No. 344,785. (No model.)

To all whom it may concern:

Be it known that We, MARTIN NELSON and GEORGE NELSON, both residing at Chicago, in the county of Cook and State of Illinois, and citizens of the United States, have invented anew and useful Improvement in Window-Screens, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a front elevation. Fig. 2 is a section, through the screen at line 2 of Fig. l,

-showing also in section so much of awindowframe as is necessary to illustrate how the screen is applied thereto. Fig. 3 is a detail in perspective. Fig. 4 is a detail. Fig. 5 is a detail. These three figures, 3, 4, and 5, illustrate how the wire-netting is secured in place. Fig. 6 is a detail showing a piece of rubber or other flexible material in connection with the screen and sash. Fig. 7 is a section at line 7 of Fig. 5. Fig. 8 is a detail showing the guide-strips.

This invention has for its object to provide a novel, simple, efficient, and economical window-screen; and to such end the invention involves the features of construction, the combinatlon or arrangement of devices, and the principles of operation hereinafter described and claimed.

In the drawings, A A represent two strips of sheet metal, which form the vertical side pieces of the front of the frame.

B B represent two other strips of sheet metal, which form the end pieces of the front of the frame.

C represents wire-netting. To secure this wire-netting to the side pieces A A and end pieces B B of the frame the inner edges of such pieces arefirst turned up at right angles to the main parts thereof, as shown in Fig. i a portion of such pieces near the ends thereof being first cutaway. Then the wire-netting is placed over such angular portions a, which then are bent over, carrying the netting with them, as indicated in Fig. 4, so that the netting is held rmly clamped between the two parts of these metal strips. Then two strips of metall) D are placed over the side pieces A A and upon the wire-cloth, as shown in Fig. 5, and corresponding strips are also placed over the end pieces, after which the front and rear side pieces and the front and rear end pieces, with the wire-cloth between them, are firmly secured in place by means of staples b, which pass through holes provided theref for, which staples are to be bent down and clinched, as shown in Fig. 5, the two endsof the staples lying side by side.

E are four corner-pieces-one at each cor-1 ner of the screen and on the front thereof-Y which are secured in place by means of screwbolts and nuts. lwo of these screw-bolts cd at each corner pass through slots ein the corner-piece, and the screw-bolt f for each cor-A ner-piece passes through slots in the side and4 end strips.

We have shown in Fig. 3 one of the slots g in the side piece A and the end slots h in one extremity of the end piece B. The slots at the remaining corners are the same as shown by the letters g h, Fig. 3, and therefore further illustration is not deemed essential. Theobject of the slots in the corner-pieces and side and end pieces is to allow a slight adj ustment of the frame to adapt it to fit the slight variations in the size of the openings which the screen is designed to ll.

F F are strips of rubber or other flexible material, which are held between the edges of th efront and rear end pieces of the frameone at the top and one at the bottom-the edges of which end pieces are bent over, so as to incline the rubber or other material, as shown in Fig. 6, which rubber is designed to come in contact with the sash, one of which G is shown, and prevent the ingress of insects and dust.

H H are sheet-metal guide-strips bent at' right angles, which strips are to be secured to the iinishing-strips on the casing to receive the screen, as indicated in Fig. 2.

The strips D D bind the side pieces A A to the netting C, and constitute guideways for the strips l-I, together with the strips corresponding to the strips D D', which are in practice used in connection with the end strips B B in the same manner as described with reference to the side pieces A A', serving to bind the strips B B to the netting and to grasp the flexible strips F F as in Fig. 6.

This screen, made of strips of metal as described, has but very little thickness and is Well adapted to be used on the inside of a Window having inside shutters or on the outside where blinds are used, and it can be used either with the upper or lower sash, and by applying four strips similar to H, two for the lower sash and two for the upper, a single screen can be used either with the lower sash or with the upper at pleasure. In applying a screen so that it may be used with both of the sashes three o't the guide-strips I-I are to be applied. The screen is then to be pnt in place, after which the fourth strip H is to be secured in place.

This screen being made of sheet metal will not shrink, swell, or Warp. The screen-cloth being held as described, the netting will be stretched tightly and will beheld securely, and by turning over the side and end pieces, to secure the netting as described, the screen is greatly strengthened.

The outside corners of the adjacent end ot' the upper and lower strips H are cut olf, as shown in Fig. S, so that the window-screen will readily pass from one guide-strip to the other.

W'hat We clai n1 as new, and desire to secure by Letters Patent, is as follows:

l. In a window-screen, the combination ot' the side pieces A A and the end pieces B B,

each having the angular portion a at its inner edge, with the netting C, the metallic bindingstraps D D', arranged over the netting, and staples b, passing through the strips, netting,

and side and end pieces, substantially as described.

2. In a window-screen, the combination of the side pieces A A', having the slots g, and

the end pieces B B', having the end slots h, each of said pieces having an angular edge portion a, with the netting C, engaging the angular portions, the metallic binding-strips D D on the netting, the corner-pieces E, hav!- ing the slots e, and the three bolts c d j, passing through each corner-piece, substantially as described.

3. In a window-screen, the combination of the side pieces A A and the side pieces B B', each having slots and angular edge portions a, the netting C, the metallic binding-strips D D', arranged over the netting at the side and end pieces, the staples b, passing through the binding-strips, the netting, and the side and end pieces, the corner-pieces E, having slots e, the three bolts c d f, passing through each corner-piece, and the guide-strips I'I, substantially as described.

4t.` In a Window-screen, the combination of side and end pieces A A B B', the netting C, the metallic binding-strips D D', arranged over the netting at the end pieces, the Iiexible strips F F, clamped between the bindingstrips and the end pieces, and staples Zi, passing through the binding-strips, the netting, and the end pieces, substantially as described.
